What to know before buying

Listing details to confirm

The listing has inconsistent length details: 20.2 metres in the product details and feature text, 66ft in manufacturer content, and 20M in the title. It also lists USB as a connection, Touch as a control method and battery power as the supply, without clarifying how these details relate. Waterproofing and IP65 are claimed but not independently established. Confirm the selected listing's configuration and colour before buying. The multicolour appearance is visible only when the lights are on.

Customer feedback highlights bright-looking multicolour lighting, appearance, available settings and perceived value. Reliability is mixed, and some customers report problems with lights stopping or remote controls. For this model, the listing describes button operation and does not establish that a remote is included, so remote-related reports may not apply to the listed configuration. Battery life is also a practical consideration because the listing warns that batteries may drain quickly.

Positive themes

Customers praise the colours, brightness, appearance and range of settings.
Some customers describe the lights as good value.

Mixed feedback

Feedback on reliability is mixed, with reports that some lights stop working.
Remote-control experiences are mixed, although a remote is not established as part of this listing.

Frequently asked questions

Are batteries included?

No. The listing says four AA batteries are required and not included.

How does the timer work?

The claimed cycle is 6 hours on followed by 18 hours off. The listing also describes a memory function for the last mode.

Can these lights be used outdoors?

The listing claims indoor and outdoor use and describes the lights as waterproof, but the protection claims are not independently established.

How long is the string?

The product details and feature text give 20.2 metres, while the title says 20M and manufacturer content also lists 66ft. The exact length is therefore inconsistent across the listing.
